Question 2:
If marked price = â¹990 and percentage of discount is 10, then find the selling price.

Question 4:
The marked price of the fan is 3000 rupees. Shopkeeper gave 12% discount on it. Find the total discount and selling price of the fan.
Answer:
12% discount is given on the marked price. Therefore, if marked price is â¹ 100, then selling price is â¹ 88.
Let the selling price be â¹ x when the marked price is â¹ 3,000.
= â¹ 2,640
So, the selling price of the fan is â¹ 2,640.
∴ Discount = Marked price − Selling price = â¹ 3,000 − â¹ 2,640 = â¹ 360
Thus, the discount on fan is â¹ 360.

Question 5:
The marked price of a mixer is 2300 rupees. A customer purchased it for Rs. 1955. Find percentage of discount offered to the customer.
Answer:
Marked price of the mixer = â¹ 2,300
Selling price of the mixer = â¹ 1,955
∴ Discount = Marked price − Selling price = â¹ 2,300 − â¹ 1,955 = â¹ 345
On marked price of â¹ 2,300, the discount is â¹ 345.
Let the discount be â¹ x.
Now, if the marked price is â¹ 100, then the discount is â¹ x.
∴
⇒ = 15
Thus, the percentage of discount offered to the customer is 15%.

Question 6:
A shopkeeper gives 11% discount on a television set, hence the cost price of it is Rs. 22,250. Then find the marked price of the television set.
Answer:
Let the marked price of the television set be Rs x.
Discount percent on the television set = 11%
If the marked price of the television set was Rs 100, then the customer would have paid (Rs 100 − Rs 11) Rs 89 for the television set.
It is given that cost price of the television set to the customer is Rs 22,250.
∴
⇒ = Rs 25,000
Thus, the marked price of the television set is Rs 25,000.

Question 8:
A shopkeeper decides to sell a certain item at a certain price. He tags the price on the item by increasing the decided price by 25%. While selling the item, he offers 20% discount. Find how many more or less percent he gets on the decided price.
Answer:
Let the decided price of the item be â¹ 100.
∴ Marked price of the item = â¹ 100 + 25% of â¹ 100 = â¹ 100 + â¹ 25 = â¹ 125
Discount on the item = 20% of â¹ 125 = = â¹ 25
∴ Selling price of the item = Marked price of the item − Discount on the item = â¹ 125 − â¹ 25 = â¹ 100
Since the decided price of the item is same as the selling price of the item so the shopkeeper neither makes any profit nor any loss on selling the item.
Thus, the shopkeeper gets 0% on the decided price.

Question 4:
Umatai purchased following items from a Khadi-Bhandar.
(i) 3 sarees for 560 rupees each.
(ii) 6 bottles of honey for 90 rupees each.
On the purchase, she received a rebate of 12% . How much total amount did Umatai pay?
Answer:
Cost of each saree = Rs 560
∴ Cost of 3 sarees = 3 × 560 = Rs 1,680
Cost of each bottle of honey = Rs 90
∴ Cost of 6 bottles of honey = 6 × 90 = Rs 540
Total cost of the items purchased = Rs 1,680 + Rs 540 = Rs 2,220
Total rebate received = 12% of Rs 2,220 = = Rs 266.40
∴ Total amount paid by Umatai
= Total cost of the items purchased − Total rebate received
= Rs 2,220 − Rs 266.40
= Rs 1,953.60
Thus, the total amount paid by Umatai is Rs 1,953.60.
